Sherrill, solid metal is neutral. Where the metal contacts the
water a electric field will strip the electron from the metal
atom and convert it into an positive ion which can desolve into
the water. Water is a very polar molecule and ions both positive
and negative stick to the water molecules. Calcium is a negative
ion when desolved in water. When the calcium ion comes in contact
with the positive metal ion it creates a molecule which is not
very soluble in water so it partcipates out. Different metals
stay in solution better than others.

explain in common english and without math just how the flow of
electric current through the ground causes a gas pipeline to
corrode?? ( Next we will tackle how a lightning strike is a
complete circuit?) - Thank's- sherrill k4own
